<p style="text-align:justify; color:blue;"><b>live.glidernet.org</b>
displays <a href="http://www.flarm.com/" target=window>FLARM</a> equipped aircraft in flight on a map. Their positions are recovered by a network of
<a href="http://flarmrange.onglide.com/" target=window> Flarm ground receivers</a> and
uploaded to this website via the InterNet. Each aircraft is represented by an icon with
a 3 character identifier (this is either its competition number, the last 3 characters
of its registration or _xx where xx is the last 2 characters of a randomly assigned hex ID).
A coloured line on the map represents the track of each aircraft. A list of all aircraft
in flight is displayed in a panel at the side of the window and shows the identifier of the
aircraft, the colour of its track, its altitude and its vertical speed (Vz).

The default condition is that all aircraft for which data has been available within the

If there has been no data for an aircraft after a period of 10 minutes then
it goes into the <span style="color:black;">OffLine</span> list.<br><br>

the aircraft on a label at the top center and highlights the track of the aircraft.<br>
